gtk:action-visible (object)

object -- a gtk:action object
visible -- true to make the action visible

Accessor of the visible slot of the gtk:action class. The gtk:action-visible function returns whether the action itself is visible. The (setf gtk:action-visible) function sets the visibility.

Note that this does not necessarily mean effective visibility. See the gtk:action-is-visible function for that. The gtk:action-visible function has been deprecated since version 3.10 and should not be used in newly written code.
